Abstract Endowing materials with specific functions that are not readily available is always of great importance, but extremely challenging. Co 4 N, its beneficial metallic characteristics, has been proved to be highly active for the oxidation water, while it notoriously poor catalyzing hydrogen evolution reaction (HER), because unfavorable d‐band energy level. Herein, we successfully endow N prominent HER catalytic capability by tailoring positions center through transition‐metal doping....
Metal sulfides for hydrogen evolution catalysis typically suffer from unfavorable desorption properties due to the strong interaction between adsorbed H and intensely electronegative sulfur. Here, we demonstrate a general strategy improve of metal by modulating surface electron densities. The N modulated NiCo
Abstract Molybdenum disulfide is naturally inert for alkaline hydrogen evolution catalysis, due to its unfavorable water adsorption and dissociation feature originated from the unsuitable orbital orientation. Herein, we successfully endow molybdenum with exceptional capability by carbon-induced modulation. The prepared carbon doped displays an unprecedented overpotential of 45 mV at 10 mA cm −2 , which substantially lower than 228 also represents best catalytic activity among ever-reported...

Abstract Although it is commonly believed that the water‐dissociation‐related Volmer process rate‐limiting step for alkaline hydrogen evolution reaction (HER) on Pt‐based catalysts, underlying essence, particularly atomic scale, still remains unclear. Herein, revealed sluggish water‐dissociation behavior probably stems from unfavorable orbital orientation and kinetic issue successfully resolved via N‐induced tuning. Impressively, N modified Pt–Ni nanowires deliver an ultralow overpotential...
